Legal Online Sportsbook Bonus Offers & Promotions

Welcome bonuses are usually the best offers you can get. Most of the time when you’re gambling on sports, you’re going to get welcome bonuses that match your deposit by 50% to 100%, for anywhere between $250 to $1000.

These betting sign-up bonus offers differ by site, but in general, the bigger the bonus, the higher the rollover (see below), while the smaller the bonus, the lower the rollover.

All the most legit legal sportsbooks usually cap their rollover requirements at a maximum of 10X, which means that – no matter how much you deposit or where you choose to play – you’ll be able to reach those requirements quickly and easily.

We always recommend accepting these offers at betting sites with welcome bonus options.

Other common promos you’ll come across are account reload bonuses. A reload bonus awards you a certain percentage of your deposit as bonus bets or free plays, which you use to bet more money more often.

These sportsbook match bonus offers aren’t always available at every site, but they usually are, and they come with the same general limits that you’ll get with welcome bonuses.

For account reloads, the best bonus bet offers will typically boost your bankroll by 40-50%, for anywhere between $500 and $1000.

To get bonus bets when adding money to your existing account, simply select the applicable box in the deposit menu or enter an active sports betting bonus code. (You can read about bonus codes and how to use them further down this page.)

Crypto betting bonuses are heavily featured at every top-rate legal online sportsbook, as crypto – especially Bitcoin and popular altcoins like Ethereum, Litecoin, Stellar, Ripple, Bitcoin Cash, etc. – are the preferred way for these operators to process your payments.

While you will get valuable bonuses with all online betting deposit methods, BTC and other cryptos always give you the most bang for your buck.

In fact, just for depositing with a supported cryptocurrency, you can often get twice or even three times the normal amount of bonus bets you’d otherwise be eligible for!

Best of all, crypto betting bonuses have the exact same rollover limits, so it’s just as easy to meet the terms and claim your payouts.

Sometimes, the best sportsbook sign-up bonus isn’t how much you get, but how much your friends get.

Most legal online sports betting sites offer friend referral bonuses that not only give your acquaintances extra cash on top of their standard bonuses, but actually give you between $100 and $125 of free plays every time a referral signs up and makes a deposit.

Sports betting referral bonuses come with very low rollovers, and if the player you get to sign up deposits with crypto, both of you will get even more money to play with.

Friends don’t let friends bet on sports without bonuses!

Many sportsbooks offer bonuses especially for mobile betting. All the most highly regarded offshore sportsbooks have spent considerable time and effort developing mobile betting sites for their members, as most bettors prefer to gamble on the go.

These smartphone- and tablet-friendly portals are responsively designed to offer pixel-perfect menus and efficient, one-touch odds browsing that works on any iPhone, iPad, or Android, regardless of screen size or make and model.

Typically, a mobile bet bonus will be offered in the form of a risk-free bet with a limit of $20 to $50. If you lose your first mobile bet, the loss is simply refunded, and there are minimal rollover requirements (or no requirements at all).

Occasionally, you’ll even find a mobile bet no-deposit bonus code so you can place your first wager completely on the house!

As with mobile betting bonuses, many sportsbooks offer promotions that give you one free live betting bonus.

Live betting is fast becoming the most popular way to bet on sports online, as it allows you to wager on all kinds of straights, spreads, totals, and props during the games themselves.

For true immersion, nothing beats in-game betting, and to get you started, you can often get a risk-free live bet. With a limit of $20-50, just place a wager on any game, and if it hits, you collect your winnings as usual. But if the bet loses, you don’t actually lose, as your wager is refunded back to your account.

These kinds of in-play betting bonuses come with minimal or zero rollover requirements, as well.

When you bet online, the best sign-up bonus betting sites will sometimes have special new-member promos (or existing member promos) that are based around particular sporting seasons or tournament/championship events.

Most books will give you things like free bracket entries, increased free bet amounts on fresh deposits, and more, all depending on the time of year.

The best times to claim seasonal sports betting bonuses are right before the Super Bowl, the World Series, the NBA Finals, March Madness, the Olympics, the FIFA World Cup, and so on.

And, as ever, if you deposit with BTC or another crypto coin, you can get even more free money!

Easily the most sought-after type of online betting bonus is the no-deposit bonus. While this perk was an early mainstay at the best Internet sportsbooks, they’re not usually available anymore except on special occasions.

However, you can still find them from time to time if you pay attention, and they’re well worth your while.

Typically, at the best online betting sites, no-deposit bonus options will be limited to new members, though if you’re returning after a long hiatus, some sites will also let existing members in on the action.

Still, if you’re specifically looking for betting sites with free bonuses on registration, you may not find them in a timely fashion. In this case, we recommend making a small deposit of between $20-$100 and accepting a standard welcome bonus.

Free sports bet bonus options of this sort come with higher rollovers than standard, but they’re still fair and easily attainable.
